IBEATING AND MIXING DEVICE.

Patented June 10, 1913 To all whom it may concern:

Be it known that I, HOWARD W. GIBBS, a citizen of the United States, residing at Boston, county ofs lfiolk, State of Massachusetts, have invented a certain new and useful Improvement in Beating and Mixing Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to beaters of the class employed particularly to beat and mix beverages of various kinds), such as are commonly dispensed at's'odafountains ahd the like, and is an'improvement on the device shown and described in Letters Patent'of the United States No. 1,046,648, dated De-- cember 10, 1912. In devices of this kind it is desirable that the beater operate as near the bottom of the glass as possible, and as glassesaver y largely in the thickness ,of the bottom it is important that the operator be able to adjust the position of the beater with the least possible expenditure of ti'meand without the use of tools.

The object of my invention therefore is to produce a device-which can be instantly adjusted by the operator.

Another object of the invention is to improve'the mechanism for the operation of the beater member so that it will be more effective and smooth in its operation, and so thatithe mechanism will be more durable.

The invention consists in certain novel features of construction and operation, all

as hereinafter more fully set forth in the.

following description of a machine embodying, my invention, and illustrated in the accompanying drawings, forming a part hereof.

Fig.2 is a front view in detail of the beat-er member operating mechanism. Fig. 3 is a detail enlarged and partly in section of the beater shaft bearing-and crosshead connecting means. F ig. 4 is a horizontal section on line 44' of Fig. 1. Fig. 5 is a modified form of a machine-embodying my invention.

Having reference to the drawings, the standard is shown atA mounted on a support 13 which. may be of any suitable construction. The standard A is hollowland is flange 3 thereby obviatin provided with a base 1 and a cap 2. Entendmg throu h'the cap 2 is an aperture somewhat sma ler-m'cross section than the inside hollow portion of the standard A into which fits a hollow plunger C. The plunger C is provided at its lower end with an outwardly extending flange3, the sides of whichjare contiguous with the inner walls of the standard A, thereby. acting together with the cap 2 as a guide whereby the plunger is maintained centrally of the standard and at the same time permitting it to be freely raised or lowered within thestandard. I regard this construction as ,important, as it reduces the frictional surfaces to two points, namely, the cap 2 and the all tendency to bind. Furthermore,- the ange 3 acts as a stop by engaging the lower side of the cap 2 to prevent the plunger from being'raised more than a predetermined distance. v

The upper end of'the plunger C is rovided with a cap.. 4.having a round ole therethrougli in which the adjustment rod 5 loosely fits so that it may be readily revo-' luble therein. -In order to prevent the rod 5 from having longitudinal movement I provide a shoulder 53 below the journal por tion 54- of the rod which abuts the lower side. of the cap 4: and I also secure a handle 6 to i the upper end of the rod which contacts with the upper surface of the cap 4 as is distinctly shown in Fig. 1. By means of the handle 6 the rod-5 may be turned. for reasons hereinafter to be explained.

The adjustment rod 5 extendsfrom the cap 4 centrally of the plunger C to a point slightly above the lower end of the plunger, as is clearly shown in Fi 1. It fits loosely into a tubular member which is secured to the base 1 of the standard A and which extends upwardly centrally of the standard and plunger sufiiciently to prevent the rod 5 from being disengaged with it'when the plunger is raised as high as it will go. When the beater isno't in use, the plunger C remains in raised position which is at a sufficient height to enable a glass or'cup to bel p1aced= beneath the beater member D. The plunger is' lifted to this position by means of along helical'push spring 8 which. is located within the plunger and standard outside of the rod '5 and the tubular member 7 having its ends 'in contact with the base 1 and the cap 4 respectively. It will be seen that by the use of a long spring practically the same lifting pressure against the plunger in'itsraiised position is obtained as in its lowered position, and it is much more durable than a short spring. I regard thisas important for in order to the most effective service itis desirable that the spring compress uniformly so that the op erator will not beobliged to exert an increased. force at any point in the movement of the plunger. In order thatthe plunger may be retained in its lowest position.

against the pressure exerted by the spring, I provide a longitudinal slot 9 in the tubu- -lar member 7 and a notch 10in the side of the slot at the lower end thereof, as shown tudinal slot 9 and a suflieient distance above its lower end. Therefore when a cup or a glass with a thick bottom is used the machine may be readily adjusted to it by causing the'pin- 11 to engage the notch 13..

Therefore by turning the red one way or the other, the desired adjustment can :be ob tained and the use of adjusting tools of any kind, which are most ,inconvenient to the operator, is entirely done away with. A forked bracket 12 extends outwardly from the standard A. and'serves toposition the glass relatively to thebeater member D.

The operating mechanism consists of ashaft 14 equipped with a crank 15 and sup ported on a bearing located on the side of the plunger C. This shaft is connected with another shaft by meansof gears lland 4-2 on the free end of which is a crankE disk 16 theshaft being supported on abearing 17, secured to one side-of the plunger ,0 by means of a bracket:1 9. The crank disk 16 is provided with a crankpin .20 (see Fig.2) on its outer face near theperipherythereof. The crank pin 20 is provided with a roll 44 which engages a horizontal groove in a cross head 21, thereby connecting the crank disk.

1 16 to a beater shaft 22 which, 'is' revolubly secured to the cross-head. 21'. .The beater shaft is spiral for part of its length and is provided at its lower' end with a beater 60 member'D of common form and ordinary construction. The spiral portion of the -beater' shaft passes through a controlling aperture'23 in the lower bracket extension 24:, theapertu're being so shaped (see FigQ 4-) that the vertical reciprocation of the loosely into a sleeve 25 to be readily revoprovided with'a-notch'rand the, 0th

apes-p rod therethrough causes the latter to revolve alternately, in" opposite directions as the beater shaft is moved up and, down. The cylindrical upper end of the rod 22 fits luble therein. The sleeve 25 nturn loosely 70 lits a guiding aperture in the upper bracket extension 26 and at its upper end has an enlarged portion wherein is a thrust hearing pocket 27, as is shown in Fig. 3. Near the upper end of the beater shaft 22 is a flange 28 which is supported'above and below byball bearings 29 and 30,'as' shown in Fig. 3, so as to effectively prevent longitudin-al movement offthe rod 22 and at the same time permit it to revolve freely; The roll 1 1 travels back and forth in the hori' zontal crosshead 21 to which the sleeve is secured, causing the rod 22 to be reciprocated when the disk 16 is rotated. The machine hereinabove described is capable of mixing the contents of oneglassj at a time only. In Fig. 5 is shown a device'gjy equipped with two beater members located on opposite sides of the standard and pluh-i '9 ger. his enables the contents of two" glasses to be mixed at the same time In order to reciprocate the beater shafts122 to which the beater members D are secured I provide two crank disks 16'. The disks 18 are connected by means ofbevel gears 47 and 19 to a central bevelgear. 48' to which a crank 50 is secured. From the description hereinabove set forth, it will beseen that the device embodying my invention comprises few moving parts, that the reciprocating "oscillating beater'shaft is supported'on a bearingdesigned particularly to withstand the strain to which it is subjected, and is therefore 105 very durable. Furthermore the device is readily adjustable and the adjusting mechanism and means for terminating the plunger movement'are wholly inclosed and therefore freedfrom. dust and dirt. lVha'tI claimisjzj I f 1.
